Ignite Cluster and Kubernetes Cluster

[narges saleh <sn...@gmail.com>]

Hi All,

Is it possible to have multiple ignite clusters within a single K8 cluster
(say AKS cluster)?

thanks.

It is possible to have multiple Ignite clusters inside a K8 Cluster.
For each ignite cluster:
  1. create a service that allows the pods within the ignite cluster to
identify each other.
  2. put the service as as spec into the statefulset/deployment yaml.
  3. put the service into the ignite discovery section.

ex(showing the first few lines of a service, statefulset, and discovery
sections): 

* cluster 1 *

apiVersion: v1
kind: *Service*
metadata:
  # The name must be equal to TcpDiscoveryKubernetesIpFinder.serviceName
  name:* gridgain1-service*
  # The name must be equal to TcpDiscoveryKubernetesIpFinder.namespace
  namespace: gridgain

stateful set
----------------
apiVersion: apps/v1
kind: *StatefulSet*
metadata:
  # Cluster name.
  name: gridgain1-cluster
  namespace: gridgain
spec:
  replicas: 2
*  serviceName: gridgain1*


*discovery section*
-----------------------------------
                <property name="ipFinder">
                    <bean
class="org.apache.ignite.spi.discovery.tcp.ipfinder.kubernetes.TcpDiscoveryKubernetesIpFinder">
                        <property name="namespace" value="gridgain"/>
*                        <property name="serviceName"
value="gridgain1-service"/>*
                    </bean>
                </property>



------------------------------------------------------------------------------------------------------

*cluster 2*

apiVersion: v1
kind: *Service*
metadata:
  # The name must be equal to TcpDiscoveryKubernetesIpFinder.serviceName
  name: *gridgain2-service*
  # The name must be equal to TcpDiscoveryKubernetesIpFinder.namespace
  namespace: gridgain
...


apiVersion: apps/v1
kind:* StatefulSet*
metadata:
  # Cluster name.
  name: gridgain2-cluster
  namespace: gridgain
spec:
  # The initial number of pods to be started by Kubernetes.
  replicas: 2
  serviceName:* gridgain2*
..

*discovery section*
----------------------
                <property name="ipFinder">
                    <bean
class="org.apache.ignite.spi.discovery.tcp.ipfinder.kubernetes.TcpDiscoveryKubernetesIpFinder">
                        <property name="namespace" value="gridgain"/>
                        *<property name="serviceName"
value="gridgain2-service"/>*
                    </bean>
                </property>

Thanks for the reply.
So, what I need is to set TcpDiscoveryKubernetesIpFinder.namespaceName to a
different namespace for each cluster and declare the namespace in the
related ignite connector service yaml file?

Yes. You should deploy them in a different namespace.
